Bitmap management method, device, equipment and readable storage medium

The invention discloses a bitmap management method. When creating a bitmap, only one copy of the bitmap is created in the program, and the operations of each thread on the bitmap are performed on this copy of the bitmap, which can effectively save storage space; at the same time, in this method, after receiving the operation request for the bitmap copy, the bitmap update operation command within a period of time is collected and executed, which can reduce performance loss. In the merged execution of the update command, the execution object is The new bitmap copy obtained after copying the bitmap copy can prevent other threads from changing the bitmap state before the business process of the bitmap copy is completed, and ensure the stability and continuity of the business process; moreover, each thread only needs to obtain As well as the address of the stored bitmap, there is no need to store a real copy of the bitmap, and there is no mutual interference between threads, which can reduce performance loss. The invention also discloses a bitmap management device, equipment and readable storage medium, which have corresponding technical effects.
